how to create captcha in codeigniter 2.1.0

How to create captcha in codeigniter 2.1.0 load helper codeigniter ? when i have model m_captcha :

    function __construct()
{
            parent::__construct();
}

    function setCaptcha()
    {
            $this->load->helper('captcha');
            $vals = array(
                'img_path'          => './asset/captcha',
                'img_url'           => base_url().'/asset/captcha',
                'expiration'        => 3600,// one hour
                'font_path'     => './system/fonts/georgia.ttf',
                'img_width'     => '140',
                'img_height'        => 30,
                'word'          => random_string('numeric', 6),
                );

            $cap = create_captcha($vals);
            if ($cap)
            {
                    $capdb = array(
                        'captcha_id'        => '',
                        'captcha_time'      => $cap['time'],
                        'ip_address'        => $this->CI->input->ip_address(),
                        'word'              => $cap['word']
                    );
                    $query = $this->db->insert_string('captcha', $capdb);
                    $this->db->query($query);
            }else {
                            return "Captcha not work" ;
                     }

                return $cap['image'] ;
}

and i have controller c_login :

   function __construct()
{
    parent::__construct();
    $this->load->model('m_captcha');
}   

    public function index()
    {
          $this->load->helper('captcha');
          $data = $this->m_captcha->setCaptcha();                            
          $this->load->view('login/v_form',$data);                        
    }

and i have view :

<?php echo form_open('c_login'); ?>
 <?php echo  $cap['image']; ?>
<?php echo form_error('captcha');?>
<?php echo form_close(); ?>

why the captcha cannot show in view ? position folder and image captcha in sms/asset/captcha . sms is folder root Codeigniter.

Why don't use reCaptcha instead? http://codeigniter.com/wiki/ReCAPTCHA It's easy to implement!

<?php echo $cap['image']; ?> is the problem.

Lets check the flow once again, you are returning the $cap['image'] from model.

And after that, you accepted that in $data in controller.

It must be something $data['capcha'] so that you can access it using $capcha in view.

Very Simple.
